Spectroscopic Observation of Matrix‐Isolated Carbonic Acid Trapped from the Gas Phase

Against all odds: Carbonic acid molecules were trapped from the gas phase in a solid noble‐gas matrix at <10 K and studied by IR spectroscopy. The 2H and and 13C isotopologues were also examined. Gas‐phase carbonic acid is thought to exist as a 1:10:1 mixture of two monomeric conformers and the cyclic dimer (H2CO3)2. This data is vital in the search for gas‐phase carbonic acid in astrophysical environments.
